NICOLAS SOHARLE AND JACOB HIMMES, OF CHICAGO, ILLINOIS.

RAILWAY TRACK-SCALE.

SPECIFICATION forming part of Letters P Application filed August 6, 1886.

To all whom it may concern.-

Be it known that we, NICOLAS SOHARLE and JACOB HrMMEs, citizens of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway Track-Scales, of which the following to the accompanying drawings.

This invention relates to devices for increasing the length of a track-scale by additional levers, and it more particularly relates to improvements on the Fairbanks railway track-scales in which heretofore such extension-levers were applied at either end of the usual scale, when, in order to make connections with the fifth-lever through the medium of the other levers, such connecting parts had to be placed below the line of supports of the other levers, where such parts were exposed to being frequently submerged by water collecting in the scale-pit, and therefore were not reliable in their balance; and it has been the object of our invention to provide a device by which a track-scale may be extended to any desirable length without any parts reaching below the horizontal line of the lever supports.

Our invention therefore consists of the novel devices and combinations of devices, as hereinafter will be described and specifically In the accompanying drawings, Figure 1 represents a sectional longitudinal elevation, and Fig. 2 a plan view, of one half of a trackscale, the other half of which being the same construction; and Fig. 3 is a detail view of the even-balance beam on an enlarged scale. Fig. 4. is an enlarged cross-section of the scale, taken on line as m, Fig. 2. Fig.5 is a detail view of the end of one of the main levers and means for supporting it.

Corresponding letters in the several figures of the drawings designate like parts.

The platform A of a track-scale of about thirty-four feet in length is generally supported by knife-edges a Fig. 4., upon four pairs of transverse or main levers, B, the space between centers of each two pairs of adjacent main levers being called a section. These main levers being pivotally suspended at their outward ends to suitable stationary brackets,

Serial No. 210,243. (No model.)

a, secured upon the foundations, their inward ends are suspended to the pivots b of longitudinal levers O and D by loops d. The le- 'vers C are pivotally supported at one end and the levers D are pivotally supported at their centers, each in standards 6, and the le vers C and D are pivotally connected at their overlapping ends f, while the ends 9 of levers D were connected by means of a loop or loops, h, with a fifth-lever, E, that connects with the weighing-beam. I

For extending this scale to have a platform of about fifty-two feet or more in length, we insert another lever, F, between each lever D and fifth-lever E, which levers F are pivotally supported at their middle by standards 0, and are coupled by loops h with one end, i, to fifthlever E, while their opposite ends, j, and the ends g of lovers D are coupled by loops to the opposite ends of an even-balance beam, G, pivotally secured at its center to a foundation-timber, L. These beams G transmit the swinging movement of levers D tolevers F, to be in proper direction for the movement of fifth'lever E again, and these levers F have each a pivot at proper distance from its fulcrum for suspending the ends of two pairs of additional main levers, B, that form the central supports for the platform A, and thus increase the number of sections to be five instead of three. More than two levers F can be thus interposed in the center for still more extending the platform lengthwise;but with each such lever F an even-balance beam, G, will be required to form the connection with the other beams.

Instead of securing the even-balance beams G upon or to the foundation, they may be fastened to the scale-platform A,which then, however, will change the multiplication in the system of scale levers.

, What we claim is- 1.. A scale comprising the following elements, to wit: the longitudinal levers G, D, and F, all arranged on substantially the same horizontal plane, and short even-balanced beam G interposed between levers D and F, and the main levers B B B and transverse lever E, arranged beneath the longitudinal levers.

2. In a platform-scale, the combination of the following elements, to wit: the longitudi- 11:11 levers O D,n1ain levers B 13,-aud transverse lever E, of one lever F and one beam G, with two main levers, 13, comprising an additional section, one or more of which sections to be interposed between levers D and E, for extending the length of the SCILlG more or less, the longitudinal levers C, D, and F being arranged on substantially the same horizontal plene,with the transverse levers B, B,

and F arranged beneath the longitudinalle- 1o vers, all as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
